mounted in pairs on beams which are oriented at right angles to the
strip's direction of movement. Different profile forms can be obtained
by shifting the pairs of work rolls along the beams and by internal
adjustment of the rolls of the pair. Presumably, test runs are then
required as well as fine-tuning before the production run of each new
profile form.
In German Laid Open Patent Appln. No. 28 16 993, a shaping machine
is described which has, in the conventional manner, whole profiled and
driven rolls which both form and drive the strip. The machine includes
different sets of rolls which can be indexed into operative position
but would appear to require relative fine-tuning for satisfactory
operation.
Although U.S. Patent No. 4,136,545 discloses a configuration for
changing the rolls by rotating them~ there does not appear to include
such changing for the purposes of changing the profile.
OBJECTS OF THE INVENTION
It is an object of the invention to provide a rolling mill machlne
capable of selectively forming plates of different cross sections.
It is another ob~ect to provide such a machine which can be conven-
ientLy and simply changed to form the different plates.
It is still another object to provide such a machine which is
inexpensive and requires no special adjustments to change the cross
section of the plate.
SUMMARY OF TXE INVENTION
These and other objects of the invention are provided in a pre-
ferred embodiment thereof including a rolling mill machin~ for longi-
tudinal bending of plate to selectively provide one of at least two
13114 a ~ NHL-SSA-02 Canada
cross-sectional profiles. The machine includes a plurality o shaping
stations extending transversely of the plate wi~h at least one drive
station for advancing the plate through the plurality of shaping sta-
tions. Each of the shaplng stations has a first -Eorming element on
one side of the plate and a second orming element on the other side
of the plate. The first forming element has at least a first set of
non-driven forming rolls and a second set of non-driven Eor~ing rolls.
The second forming element has a plurality of non-driven forming rolls.
The first forming element is selectively moveable to position at least
one o the first and the second sets thereof for bending of the plate.
The rolls of at least one of the first se~ and the second set are
disposed for forming the plate on one side and the rolls of the second
forming element are disposed for forming on the other side. The first
set of rolls of the first forming element is for cooperating with the
rolls of the second forming element to bend the plate to form a first
of the cross-sectional profiles while the second set of rolls of the
first forming element is for cooperating with the rolls of the second
forming element to bend the plate to form a second oE the cross-sec-
tional profiles.
One aspect of the invention resides broadly in a rolling mill
machine for bending of plate along the longitudinal axls of the plate
as the plate is moved along a path which is generally parallel to the
longitudînal axis of the plate through the rolling mill machine to
selectively provide one of at least two cross-sectional proiles
comprising: a plurality of shapîng stations positioned adjacent to
said path of said plate through the rolling mill machine; at least one
drive station for advancing said plate through said plurality of said
shaping stations; each of said shaping stations having first formin~
means on one side of said plate and second forming means on the other
side of said plate; said first forming means having at least a first
set of substantially a~ially spaced non-driven forming rolls and a
NHL~S sa- 02 Canada
second set of substantially axially spaced non-driven forming rolls,
each of the forming rolls of the first and second sets being mounted
on a separate support; said second ~orming means havin~ a plurality of
substantially axially spaced non-driven forming rolls, each of the
forming rolls of the second forming means being mounted on a separate
support; said first forming means being selectively moveable to
position at least one of said first and said second sets thereof for
said bending of said plate; said rolls of at least one of said first
set and said second set being disposed for forming said plate on said
one side and said rolls of said second forming means being disposed
for forming said plate on said other side; said first set of said
rolls o said first forming means for cooperating with said rolls of
said second forming means to bend said plate to form a irst of said
cross-sectional profiles; and said second set of said rolls of said
first forming means for cooperating with said rolls of said second
forming means to bend said plate to form a second of said cross-
sectional profiles.
According to the invention an inexpensive and simple machine is
obtained which prGvides a fast and adjustment-free change between
different profiles. The invention is characterized by the fact that
in each of the shaping stations the row of work rolls on one side of
the strip or plate is supported by a first ro-tatable beam, which must
support also at least one other row of work rolls. The work rolls of
both o these two rows may respectively extend at different distances
from the rotating shaft of the first beam. The row of work rolls on
the other side of the strip is supported by another rotatable beam,
which also supports at least one other row of work rolls. The work
rolls in these two rows extend an equal distance from the rotatable
